Opengl perspective view matrix fisheye effect
WebMatrix types can be identified by tracking the OpenGL commands used to create them. This can be simple if glTranslate, glScale, and glRotate commands are used. If glLoadMatrix or glMultMatrix are used, it's still possible to rapidly check the loaded matrix to see if it matches one of the common types.

The perspective projection is very familiar to us as human beings, because our eye produces such a perspective projection. An important attribute of the perspective projection, in contrast to the parallel projection, is that objects at a larger distance to the viewer or camera are displayed smaller.
WebThe perspective projection can be constructed with glm::perspective (fovy, aspect, near, far);. The first parameter gives the field of view angle. The angle is defined in radians if you have set #define GLM_FORCE_RADIANS. In our script, we have used a field of view angle of 45 degrees (pi/4 in radians).
